Overheating problems.

[Eunys]

You are really pushing that old card to hard(it's even the bare minimum of the system requirements for FFXIV), if you look at other heat related threads in this forum you will find that this game is not very optimized right now and really taxes even newer cards. As Okiura has said start with removing any OC settings you have made. Second do the standard check case/fans/card itself for dust, most 8800's are rated for 100c I've found, so 90c+(as you said it's going over 90) is getting pretty close to their threshold. If your financial situation permits it I'd look into updating that card as well, there is plenty of great cards in the $100-$130 range.


Edit:

How long can I play the game without suffering on the long run or is it advised to play on like 2 hour intervals to avoid my gpu to being fried. Thanks

Without knowing your plans of an upgrade being possible and just running it into the ground in the meantime, I would actually advise not playing at this state, you will eventually run into artifacting then eventual death of the card.
